    Abstract: Methods for preparing phosphonium salts by reacting a primary phosphine or a secondary phosphine with an ester compound selected from the group consisting of: a phosphate triester; a phosphonate diester; a sulfate diester; and a sulfonate ester; to form a phosphonium salt of formula VII wherein each of RQ, RX, RY, and RZ is independently hydrocarbyl and X− is a phosphate, phosphonate, sulfate, or sulfonate are provided herein. These phosphonium salts may find utility in a wide range of applications, including as surfactants, as polar solvents (ionic liquids), as antimicrobial agents, and as a component of spinning finish in polyamide fibre processing.

    Abstract: A liquid binder composition for binding fibrous materials in the fabrication of resin-infusible preform is disclosed. The binder composition is an aqueous dispersion containing (a) one or more multifunctional epoxy resins, (b) at least one thermoplastic polymer, (c) one or more surfactants selected from anionic surfactants, nonionic surfactants, and combinations thereof, (d) water, and is essentially free of organic solvents. Also disclosed is an emulsification process for producing the liquid binder composition.
